shed base

[shrimp]

I have a shed in my garden that has slow subsided in to the ground,the shed is on slabs that were laid on top of sand and cement.
What i was wondering if i moved the shed to another place in the garden would it be ok on sleepers the will be rested on top of some breeze block or is this going to make it sink again.
The shed is 6'X8 '
Cheers dazz

no idea.

but the reason it sank is not the shed, its what the cement etc you have is on top of, perhasps you could put "piles" in where the shed is now?

The sand and cement base was probably laid on uneven ground, the base has then washed away over time leaving gaps for the slabs to fall into.

The best thing to do would be to move the shed, lift the slabs and level/compact the uneven ground, then shutter up and lay 4" of concrete with a sheet of mesh in there for good measure. Won't be as expensive as it sounds if you can hire/borrow a cement mixer for a weekend.
